===== Cards on a table =====

You have 8 cards: two Aces, two Kings, two Queens, and two Jacks. You need to place then on a table in the following arrangement:

       X
   X X X
     X X X
       X

In addition, you need to follow these five rules: \\
1: Each Ace must be adjacent to a King \\
2: Each King must be adjacent to a Queen \\
3: Each Queen must be adjacent to a Jack \\
4: Queens cannot be adjacent to an Ace \\
5: Two of the same card cannot be adjacent to each other \\

For this problem, adjacent means horizontally or vertically next to each other. ((Ricahrd Black, May 13))

===== Maze =====

Find your way through this maze. Enter from the bottom left, and exit from the bottom right. There are two restrictions: you must pass through the circles in alternating order (empty, filled, empty filled etc) and you must pass through any circle you touch.((Jay Brady, May 20))

===== Pluto =====

The Earth completes one revolution around the Sun in about 365.25 days. An alien sits on Pluto with a very powerful telescope and watches the Earth. From the alien's point of view, how many rotations does the Earth make in one revolution around the sun? ((Dr. Jeffs, May 27))
